چکیده
The first synthesis of cytotoxic (-)-taiwaniaquinone A and (-)-taiwaniaquinone F has been achieved through the intramolecular aldol condensation of a ketoaldehyde and the oxidative cleavage of an isopropylidene ketal.

Divergent total synthesis of taiwaniaquinones A and F and taiwaniaquinols B and D.
A divergent approach was developed toward the total synthesis of taiwaniaquinoids. An advanced intermediate 5a with trans A/B ring junction was concisely assembled by employing a Bi(OTf)3-catalyzed cationic cyclization and a Wolff-type ring contraction as key steps. This common intermediate was readily converted to racemic taiwaniaquinones A and F and taiwaniaquinols B and D, respectively.
متن کاملEnantioselective total synthesis of plakotenin, a cytotoxic metabolite from Plakortis sp.
The first total enantioselective synthesis of plakotenin is described. This marine natural product was isolated from an Okinawan sponge of the genus Plakortis and shows potent biological activity against several cancerous cell lines. A biomimetic intramolecular Diels-Alder reaction served as a key step in the total synthesis. The synthesis proves the relative and absolute stereochemistry of nat...

A highly efficient and convenient procedure for the enantioselective synthesis of (S)-Rivastigmine tartrate, a cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer’s disease, is accomplished by the treatment of versatile, readily accessible N-Ethyl-N-methyl carbamoyl chloride with 3-hydroxyacetophenone under ultrasonic irradiation in presence of nano-K2CO3 were repo...
متن کاملEnantioselective total synthesis of (+)-gigantecin: exploiting the asymmetric glycolate aldol reaction.
The enantioselective synthesis of the potent, selective, cytotoxic, annonaceous acetogenin, (+)-gigantecin, has been completed. An asymmetric glycolate aldol serves to establish the stereocenters at C13,14 and at C21,22. A Carreira asymmetric acetylide addition is used to establish the C17 stereocenter.
متن کاملThree-component procedure for the synthesis of new chiral spirooxindolopyrrolizidines via catalytic highly enantioselective 1,3-dipolar cycloaddition
The catalytic highly regio-, diastereo-, and enantioselective synthesis of a small library of spiropyrrolizidineoxindolesvia a four-component 1,3-dipolar cycloaddition reaction of azomethine ylides, derived from isatin, with electron-deficient dipolarophilewas described. The process occurs at room temperature in aqueous ethanol as a green solvent and in the presence of a bidendatebis(imine)–Cu(...
